We have a bunch of domains (over 40) that expire at different dates throughout the year. We would like to be able to co-term these so that they all expire on the same date every year, so we only have to go through the process once a year and only make one payment. Other registrars offer this (see http://www.aitdomains.com/faq.php#a10 ) and for a corporation it makes sense to have. It could even provide an incentive to stay with Dynadot as opposed to transferring to a registrar that supports this feature.
